How to apply the generateblocks_do_content Filter?

Hi there,

Is there any particular reason why it has to be added through a filter?

If I may suggest:

There's a shortcode block within the Block editor which you can place your shortcode in and make it run inside a GB container block. You can try using that instead of doing a shortcode.

Hey Elvin,

thank you for your response and your smart idea!

After a break I noticed a bigger problem: I didn't parsed the blocks in the code below. Sorry for that! :( I have changed the related PHP code to this:

<?php foreach ($heroes as $post): ?>
	<?php if(has_blocks($post)): ?>
		<li class="glide__slide">
			<?php
			foreach($blocks = parse_blocks($post->post_content) as $block):
				echo render_block($block);
			endforeach;
			?>
		</li>
	<?php endif ?>
<?php endforeach ?>

Now the html source code seems to be correct, but the css classes from GeneratePress are still missing. I have regenerated the css files and cleared my cache. Unfortunately embedding the shortcode via the Shortcode block not shows an effect.

Hello again,

this solution works:

function heroesSlider() {
	# get posts
	$args = array(
		'numberposts' => -1,
		'post_type' => 'heroes',
		'post_status' => 'publish',
		'orderby' => 'rand'
	);
	$heroes = get_posts($args);

	ob_start();

	# loop the slides
	if(!empty($heroes)):?>
		<div class="glide">
			<div class="glide__track" data-glide-el="track">
				<ul class="glide__slides" style="margin: 0">
				<?php foreach ($heroes as $post): ?>
					<?php if(has_blocks($post)): ?>
						<li class="glide__slide">
							<?php
							foreach($blocks = parse_blocks($post->post_content) as $block):
								$block = render_block($block);
								echo $block;
							endforeach;
							?>
						</li>
					<?php endif ?>
				<?php endforeach ?>
				</ul>
			</div>
		</div>
		<script>
			new Glide('.glide').mount()
		</script>
	<?php
	endif;
	return ob_get_clean();
}
add_shortcode('heroes', 'heroesSlider');

/* add css classes  */
function doHeroesCSS($content) {
	global $post;
	# check if shortcode is used
	if(is_a($post, 'WP_Post') && has_shortcode($post->post_content, 'heroes')):
		$args = array(
			'numberposts' => -1,
			'post_type' => 'heroes',
			'post_status' => 'publish',
		);
		$heroes = get_posts($args);

		if(!empty($heroes)):
			foreach ($heroes as $p):
				if(has_blocks($p)): 
					$content .= $p->post_content;
				endif;
			endforeach;
		endif;
	endif;
	return $content;
};
add_filter('generateblocks_do_content', 'doHeroesCSS', 10, 2);

But if there is more efficient solution instead of looping the content two times I am interested :)

The code is pretty straightforward. A shortcode w/ a query and a filter that appends the shortcode to the content.

It looks fine. :D

Is it fully sorted out for you? Let us know.
